Abstract
This paper demonstrates the results of study in relation to increasing the efficiency of the maintenance department of the mining company. We consider the systematic and complex approach to estimating the activities of the maintenance department, which is based on analyzing the efficiency of the arrangement for repairing and maintaining the mining machinery, evaluating the practicability of its operation according to the ratio ‘result/expenses’, studying the structure of the maintenance personnel and also evaluating the influence of operating modes and conditions on the productivity of machinery. This approach allows to find out the hidden reserves in the organizational, technical, technological and economic systems of the company. In addition, we demonstrate the results of evaluating the system ‘excavator-cut face’, which characterize the condition of an excavator and conditions (cut face, working area) of its operation, perform the analysis of the downtime of the equipment during the maintenance and when it breaks down. We consider the systematic approach to estimating the economic practicability of operating and repairing the mining machinery, which allows to make managerial decisions in relation to every unit of machinery. Also the recommendations for increasing the efficiency of the maintenance department of the company are given.
